Missing Markets for Human Capital and Differences in Growth

Standard growth models predict that consumption and GNP growth rates should not differ among countries when international capital markets are considered. This paper introduces a generational structure which implies that the return on human capital exceeds the return on physical capital in equilibrium. Thus, when the return on human capital differs internationally, the growth rates of consumption and GNP vary across countries even when there is free capital mobility. Furthermore, GNP and GDP grow at the same rate within a country, there is positive investment in every country, and poverty traps persist in spite of international capital markets
